The immediate answer to is jail time possible for speeding 100+ mph in SLO County, CA is no.
Speeding over 100 mph in California is a major traffic infraction. The primary distinction between a misdemeanor and an infraction is the potential for jail time or probation.
“A misdemeanor is a type of offense punishable under criminal law. A misdemeanor is typically a crime punishable by less than 12 months in jail.”—Cornell Law School’s Legal Information Institute (LII).
However, the penalties and financial consequences for speeding more than 100 mph are harsh.
If you were cited for speeding 100+ mph in SLO County, CA, you’re not alone. Many drivers are stopped along US-101, Highway 1, and Highway 41, where CHP patrols are active.
The penalties are steep, and a conviction can affect your record for up to seven years. Likewise, you can expect a significant rise in your insurance premium after a conviction. But you don’t have to face it alone.
The Penalties for Speeding Over 100 MPH
California Vehicle Code (VC) Section 22348(b) makes this a major infraction. These base fines range from $300 to $500, but surcharges and assessments bring the total to between $859 and $2,137.
That’s just the start. After a conviction, the DMV adds two NOTS points that remain for seven years.
Judges may suspend your license for 30 days, even on a first conviction. Insurance increases could double or triple your premium.
Why Judges Take These Tickets Seriously
Driving this fast isn’t just illegal. It’s very risky. A sudden tire blowout, a stray animal or debris on the highway, and an abrupt lane change at 100 mph can end in tragedy.
CHP officers patrol aggressively in San Luis Obispo County because these roads include sharp grades and heavy tourist traffic. Judges in Paso Robles, Grover Beach, and San Luis Obispo Courthouse recognize the danger and rarely go easy on offenders.
For reference, September 30th is the anniversary of James Dean’s death in his Porche on what is now Highway 41 in SLO County.
Could Jail Time Really Happen?
While most cases lead to fines, points, and suspensions, courts treat speeding 100+ mph differently than minor speeding.
If there are aggravating factors—like reckless driving, speed contests, or injuries from accidents and endangerment and jail could be on the table if the law enforcement officer (LEO) writes another ticket.
That’s why having an attorney is critical.
The Real Cost of a Conviction
Many drivers only see the fine, but the long-term costs are much higher. Insurance premiums often double or triple.
The average Californian, according to Bankrate.com, is already paying $2,440 annually for full coverage insurance in SLO. Imagine adding nearly $5,000 to your annual premium next year—and for seven years after.
Over seven years, this can mean thousands in extra premiums. One ticket could add $20,000 or more in expenses.
Why You Shouldn’t Self-Represent
Although the final decision is up to you, some drivers think they can explain their way out of the charge. Judges often see that as not taking the offense seriously.
Court appearances are mandatory for speeding 100+ mph in SLO County, CA. Without a lawyer, drivers risk harsh penalties they may otherwise have avoided.
Building a Defense
An experienced traffic attorney looks for weaknesses in the state’s case. Calibration errors, RADAR/LIDAR or pacing issues, or officer testimony inconsistencies may raise doubt.
Sometimes, a dismissal is possible. Other times, a lawyer can negotiate a reduced penalty or alternative outcome.
